I use shimmeron wand. And I have a question.
I use Mind Over Matter and Mind of Council helmets and clock of defiance and Clarity watcher jewel

If I get a lightning damage, the above gears will work and I have to use 11% life and 89% mana. but taken only life

Is this intended? Is not it?

Thanks for your report, we'll take a look into this.

EDIT:
This seems intentional due to the wording on "Mind of the Council".
"30% of Lightning Damage is taken from Mana before Life when hit"
Because Shimmeron's Lightning Damage isn't a hit but a degen, Mind of the Council will not work here.
